Speakers

Pete Barlow is a Principal Geotechnical Engineer with BGC Engineering out of Edmonton. He is a senior specialist in the geotechnical aspects of trenchless technologies and particularly HDD, and has been involved in several hundred projects in widely ranging environments since the mid-1990's. This has involved assessments at the routing stage to catch and avoid problematic crossing locations early; detailed geotechnical investigations to support HDD designs; construction support; assessment and mitigation of challenging HDD's encountering ground related problems; and risk assessments at planning stages to control exposure to construction projects where multiple HDDs are planned. He has also been involved with pipeline integrity issues with existing HDD installations interacting with geohazards, including a number of pipeline ruptures.

Dr. Tamer Elshimi is a Senior Geotechnical Engineer and Associate of Thurber Engineering Ltd. and has over 19 years of academic and industrial experience in the field of geotechnical engineering. Dr. Elshimi completed his B.Sc. in Civil Engineering and M.Sc. in Geotechnical Engineering in Egypt between 2000 and 2006, and his Ph.D. in Geotechnical Engineering from Queen's University in Kingston, Ontario in 2011. His research focused on the performance of deep foundations, buried pipes and culverts up to their resistance limit using the finite element method.
Dr. Elshimi joined Thurber's Edmonton office in July 2011 and has been involved in a wide variety of high-profile geotechnical assignments for infrastructure, industrial, municipal and transportation projects. He is currently the numerical modeling lead engineer at Thurber's Edmonton office. He has performed 2D and 3D finite element analyses for various geotechnical applications, including trenchless installations (HDD, pipe ramming, direct pipe, pipe bursting), tunnels, micro-tunnels, long span culverts, shallow and deep foundations, embankments on soft soils, ground improvement, slope stabilization and retaining structures.
Dr. Heinrich Heinz is a graduate of the Universities of São Paulo and Alberta, with a career spanning 40 years in Canada and abroad. He joined Thurber Engineering in Calgary in 1995, where he worked on a wide variety of projects, emphasis on tunnelling and trenchless technologies. He has authored or co-authored over 40 technical papers and has acted as an expert witness on geotechnical matters related to underground construction. He has participated in many technical and professional organizations and is a past Director of the Tunnelling Association of Canada. He is currently a member of Working Group 19 of the International Tunnelling Association, which is preparing a set of guidelines for planning, design, and construction of conventional tunnels in urban settings.
Dr. Heinz served as Thurber's managing director from 2008 to 2015, when he retired from full-time work to become a specialist tunnelling consultant.
Carrie Murray is a geotechnical engineer specializing in trenchless crossings, geohazard landslide assessments and remedial design for linear projects. She has completed hundreds of complex HDD projects providing feasibility assessments, design and construction support. Her experience also covers crossings utilizing other trenchless methods such as Direct Pipe, microtunneling, auger boring and pipe jacking.
She has eighteen years of experience as a consulting engineer (four years with Stantec in Edmonton) and two years with an HDD contractor as a geotechnical SME. Her trenchless work is primarily focused in Western Canada but she has worked on several projects throughout North America and abroad.
Carrie is active in the trenchless industry and has authored several papers in the area of trenchless geotechnical and construction risks. She also volunteers with the North American Society of Trenchless Technology as a member of the NoDig Review Committee and with CEPA and API as a technical expert with the HDD Design Guideline Working Group. She has recently contributed to the chapter on Trenchless Techniques for Pipeline Installation included in the 2nd revision of the book ASME Pipeline Geohazards: Planning, Design, Construction, Operation released in 2019. Carrie has a Bachelor Degree in Geological Engineering from the University of Saskatchewan and a Masters of Engineering in Geotechnical Engineering from the University of Alberta.
She is a Saskatchewan farm girl at heart and still gets a kick out of digging holes.
